The dynamics of growth cone morphology

Table 1 Summary of datasets used

	Cell type	Time step	Duration	Movies	Frames
In vitro (no gradient)	Rat SCG	15 s to 1 min	2 to 8 h	163	25,461
Pipette assay	Rat SCG	1 min	1 h	191	11,801
In vivo	Zebrafish RGC	1 to 10 min	1 to 24 h	27	2,249

Time step is the frequency of image capture. Each movie is for a different growth cone. RGC, retinal ganglion cell axons (approximately 2 days post fertilisation); SCG, superior cervical ganglion axons (early postnatal).
